For more information on single-ended inputs, refer to the Guide to Signal Connections (this document is

Analog voltage output terminals (VDAC0_F, VDAC0_S, VDAC1_F, and

VDAC1_S)

You can connect up to two analog voltage outputs to screw terminal pins VDAC0_F and VDAC1_F.

You may also use the VDAC0_S and VDAC1_S when you enable the remote sensing option for the output

channel. Refer to the pinout diagram on page 14 for the location of these pins.

You can enable remote sensing for each analog output on the USB-1608HS-2AO with InstaCal.

The remote sensing feature compensates for the voltage drop error that occurs in applications where the USB-

1608HS-2AO's analog outputs are connected to its load through a long wire- or cable-type interconnect.
